Imidazo[4,5-f][1,10]phenanthroline based luminescent probes for anion recognition: Recent achievements and challenges

Pyrenyl-Substituted Imidazo[4,5-f][1,10]phenanthroline Rhenium(I) Complexes with Record-High Triplet Excited-State Lifetimes at Room Temperature: Steric Control of Photoinduced Processes in Bichromophoric Systems

“…In the current contribution, we present photophysical properties of bichromophore Re­(I) carbonyl complexes with 2-(1-pyrenyl)-1 H -imidazo­[4,5- f ]­[1,10]­phenanthroline (pyr-imphen) and 1-(4-(methyl)­phenyl)-2-(1-pyrenyl)-imidazo­[4,5- f ]­[1,10]­phenanthroline (pyr-tol-imphen). The great advantages of imidazo­[4,5- f ]­[1,10]­phenanthrolines are their prominent antitumor and luminescence properties, as well as the convenient synthesis along with the possibility of introduction of all types of substituents into the imidazole ring at H1- and C2-positions, directly (via the covalent bond) or through an aryl/heterocycle bridge. , Although imidazo­[4,5- f ]­[1,10]­phenanthrolines have been combined with various transition metal ions, , [ReCl­(CO) 3 (R-imphen)] systems have been rarely investigated, and their photophysics is unfathomable. − …”

ESIPT-based probes for cations, anions and neutral species: recent progress, multidisciplinary applications and future perspectives

“…Small analytes (cations, anions and neutral molecules) are essential for biological functions in living beings. [20][21][22] These analytes play an important role in maintaining the cardiovascular system, central nervous system functioning, enzyme regulation, gene expression, ion-transport mechanism, generation/bio-synthesis of gasotransmitters, DNA repairing etc. and therefore optimum concentration must be maintained in the body.…”

Turn-on detection of Al3+ and Zn2+ ions by a NSN donor probe: reversibility, logic gates and DFT calculations

“…In recent years, fluorescent probes have seen a gradual development and advancement in highly efficient, microscopic and real-time analysis. 43–45…”

“…In recent years, uorescent probes have seen a gradual development and advancement in highly efficient, microscopic and real-time analysis. [43][44][45] Although a great number of uorescent probes have been developed for monitoring of Al 3+ and Zn 2+ ions in vitro and in vivo, [46][47][48][49] several Al 3+ -responsive probes suffer from the tedious and laborious multi-step synthetic routes. [50][51][52] Consequently, sensors with structural simplicity are increasingly being developed, and are still in high demand.…”
